Hi, i have a gateway m275. a few weeks ago it started responding eratically to the pen, ie the pointer would jump around instead of moving smoothly. i went through the motions with gateway and ended up having to send it in for repair. i got it back last week and it worked fine for about 5 days. now it wont respond to the pen at all. the touchpad still works fine. i uninstalled the wacom pen driver then reinstalled it, that didnt work. nothings changed software wise since the time it worked and then stopped. i just wanted to know if anyone had any suggestions of something i should try before i have to call gateway, yet again.
